- nannerNo-nnoxnnl 1 Application filed February a To all whom it may concern:

Be it known that I, JOSHUA B. RICK/mos, a citizen of the United States, residing 1n Philadelphia, Pennsylvania, have invented certain Improvements in Dredging-Buckets,- of which the following is a specification.

My invention relates to certain improve-. ments in hoisting buckets of thetype known as orange peel buckets. These buckets are usually provided with a series of tapered blades which, when closed, form the body. of the bucket and when open form sharp prongs which enter the soil. y,

The object of my invention is to make a comparatively light and yet substantial bucket of this type and one which will carry more soil than those constructed in the ordinary manner. The main portions of the bucket are madeofsteel cast and consequently can be made much lighter than where portions of the bucket are made of sheet metal and heavy castings. This. obj act I attain'in the following manner, reference hein had to the accompanying drawings, in whi 1:-

Figure 1, is-a view in elevation showing the bucket closed; one of the blades of the bucket being shown in section and another blade being removed; Fig. 2, is a view similar to Fig. 1, showing the bucket open withv one of the blades removed; Fig. 3, 1s a plan view of the u per head of thebucket; 4, is a. detache side view of one of the blades or" t 1e bucket; Fig. 5, is a sectional view on the no 5-5, Fig. 4; Fig. 6, is a plan view of one of the blades; and Fig. 7, is a plan view of the lower head of the bucket.

A is the lower head of the bucket; B is the up er head and D, D are the blades made taperei as shown'in Fig. 4:. These blades have arms d which are pivoted at a. to brackets a on the head A; these arms are cast integral with the blades D and extend a-con siderable distance above their upper ed e when in the closed osition, as illustrated inv Fig. 1, so as to be a 6% the level of themes: terial in the bucket. The arms preferably" extend down on the side of the blades and reinforce the body of each blade, as shown at d, Fig. 1. ugs 0!" project from the upper edge of each blade and a rib (1? ex-' tends on the outside of the blade from the lugs to the oint, as shown in Fi 2, so as'to reinforce te lower portion of the blade. The edges d of the blade are beveled to" form cutting edges. When the bucket is v of the pinsb extends entirely the head '13.

I claim; I 1. The combination in a hoisting bucket tapered blades, said blades having upwardly projecting arms, the upper ends of the arms extending toward a central line drawn through the bucket, a head pivoted to the arms, said head and the inwardly extending portions of the arms being located above around which the chain passes, and a wheel passes, with an the load line of the from the upperedge of each blade, asecond head, links Y connecting the said head with 7 the lugs, and actuating incansconnectcd to the twoheads for opening and closing the I bucket.

2. The combination in a hoisting bucket of j the orange peel type, of ,a series of tapered, curved blades having curved arms projecting from the upper edge of. the blades and extend ing toward the center of the bucket, lugs projecting outwardly from the upper edge of each blade, an upper head and a lower head, the arms being pivoted to the lower head, links connecting the'upper head with the lugs, a closing chain attached to the lower head, a wheeLonthe upper head on the lower head around which thejchain opening chain attached to the upper head.

3. The combination in a hoisting bucket of I the orange peel. type having a series of tapered and curved blades, arms projecting from the upper edge of the blades and toward the center of the bucket, and means for I opening and closing the bucket, said blades and arms being made integral. l

4. The combination in a hoisting bucket of I the orange peel type, of a series of tapered l and curved blades, each blade having an integral arm projecting from its upper edge and curved inwardly the inner side of the the arm extending onf blade 'a given distance i to form a strengthening rib, lu 's on the back of the blade, a rib extending irom the lugs j to the point, said arms,lugs and ribs being made integral with the blade, and mneans connected with the several parts by which the blades are operated to open and close the bucket.

5. The combination in a hoisting bucket of l wardly extending lug on its upper edge, two below the other, the arms,

heads, one mounted of the blades being pivoted to the lower head,

and links connecting the lugs to the upper head, the upper ends of the arms being lforked I so as to. form a double hearing at the upper head to twisting.

6. The combination in a hoisting bucket of the orange peel type, of a series of tapered and curved blades made of cast steel and haying integral arms and inwardly,

edge of the blade being beveled to form a cutting edge, upper and lower heads, the u per heads being pivoted to the arms, lin s connecting the 'upper head with the lugs on the blade, andmcans for opening'and closing ated midway between thearms, a rib on the outside of the blade extending from the lugs to the point thereof, upper and lower heads, the lower head being shaped to receive the arms of each blade, pins connecting the head withthc blades, forked at their pins connecting said arms with the u head, with means-for ac,tuatingthe hea s to open and close the bucket.
